At the start of the trailer we find Tony sitting alone with his helmet in front of him, using it to record a message for Pepper Potts.

Instead of going gooey over the emotional moment, some had more pressing concerns like – how could Tony take his helmet off if his suit is created from Nanotech?

So I’m rewatching Avengers and just noticed in this scene (not the greatest quality gif) how Tony’s glasses are nanotech. They just disappear into his armour! He didn’t even need to take them off, but did it because he’s that cool. pic.twitter.com/8zaI8ec71u

In Infinity War his helmet did get damaged as Thanos pumelled him into the ground on Titan, so that could have thrown the Nanotech off-kilter, leaving him able to take it off.

Alternatively it could be a totally different suit. We’re assuming the scene with Tony follows on directly from the end of Infinity War – what if what we’re seeing happens much later on after Tony could nip back and get a new suit.

With this supposedly being the final film in the current Avengers saga, it would be fitting for him to finish it in an old school suit like the Shell-head we first met back in 2008.

However this person has a good point.

He made the first Iron Man suit in a cave with spare parts. I’m sure he used the remaining nanotech to repair the helmet to message Pepper.

Tony says: ‘A hostile alien army came charging through a whole in space. We’re standing three hundred feet below it. We’re the Avengers. We can bust arms dealers all the live long day but that, up there, that’s the endgame. How are you guys planning on beating that?’

Is this a sign that we’re about to lose one of Earth’s Mightiest Heroes next year? We hope not…

Avengers 4 will hit UK cinemas on 26 April 2019.
